Breaking: The 49ers will face the Seahawks without All-Pro left tackle Trent Williams and rookie receiver Ricky Pearsall. I can confirm both have been ruled out for tonight’s NFC West showdown. The team has also elevated a veteran offensive tackle from the practice squad to bolster depth at the edge of the line. Tight end George Kittle was listed as questionable earlier this week, and his status will be watched right up to kickoff.
This is a major shift only hours before kickoff. Protecting Brock Purdy just became the story of the game. The 49ers will need to adjust their calls, their timing, and their matchups against a creative Seattle front.

What It Means For San Francisco’s Offense
Williams is the blind-side anchor and the tone-setter in the run game. Without him, everything looks different. Expect the 49ers to speed up the ball and lean into rhythm throws. Screens, slants, and quick outs should be featured early to keep rushers off balance.
Christian McCaffrey becomes even more central. He will be used as a runner and a pass outlet. Deebo Samuel and Brandon Aiyuk will need to win fast. Their releases and yards after catch can reduce long-developing plays.
If Kittle is active, his role may tilt toward help on the edge. He can chip at the snap, then release late. If he sits, the backup tight ends will inherit extra blocking work, and the middle of the field becomes Jauan Jennings’ stage.
Watch the first two San Francisco drives. If the ball is out in under two seconds, the quick game plan is on.
The Protection Plan Without Williams
Jaylon Moore is the likely starter at left tackle, with the elevated veteran available as insurance. The plan will not be to isolate that position for long stretches. Look for slide protections to the left, backs scanning to that side, and condensed formations that shorten the edge.
Play action can still work, but it must be balanced. Naked boots carry risk if the end does not bite. Expect Kyle Shanahan to build off toss looks, misdirection, and motion that forces Seattle to hesitate. The goal is simple, reduce straight dropbacks where rushers can tee off.
Key offensive adjustments to watch:
- More chips from tight ends and backs
- Heavier use of motion and bunch sets
- Quick game on early downs to stay on schedule
- Screens and draws to punish overaggression
Seattle’s Counter And The Coaching Chess Match
Seattle’s defense under new head coach Mike Macdonald thrives on disguise. He sends pressure without committing extra rushers. That means creepers, late movement, and zone pressures that look like blitzes. Purdy must trust his eyes and his timing. Identify the hot answer, then rip it.
The Seahawks want to squeeze the pocket from the left side and force Purdy to drift. If San Francisco’s tackles hold up just enough, Seattle will test the interior with stunts. Communication inside becomes a premium. The 49ers will counter with tempo and formations that declare coverage.

Kittle Watch And The Passing Tree
Kittle’s status matters on two fronts, protection and structure. With Pearsall out, there is one fewer route runner to stress the seams. If Kittle can go, he expands the menu on third down. If he cannot, Jennings becomes the chain mover and Aiyuk’s target share spikes.
This is where Shanahan’s receiver blocking also matters. Those perimeter blocks convert short throws into chunk gains. Deebo’s physical style can tilt a drive. Small details, like crack tosses and jet action, can slow rushers and help the tackles.
Cadence and discipline will decide hidden yards. False starts and holds on the left edge could swing this game.
Rivalry Stakes And What Decides It
This is classic NFC West football. It is rugged, calculated, and emotional. Every yard feels like a fight. The 49ers still have stars across the board, but this is a test of adaptability. Can they protect well enough to let their skill players take over. Can they run it effectively without their best run blocker.
Shanahan will try to turn this into a space game. Motion, angles, and quick hitters can steal first downs. Seattle will try to muddy the picture and win with disguised four-man rush. The first explosive play might come off a screen or a double move set up by all that quick action.
The margin is tight, and the identity is clear. San Francisco wants to stay on schedule and keep Purdy clean. Seattle wants to force long third downs and make the left tackle spot blink. I expect the 49ers to mix pace, change the launch point, and let McCaffrey shoulder the load until the dam breaks.
Conclusion: The trenches are the headline. With Williams out and Pearsall sidelined, the 49ers must be sharp, fast, and disciplined. If they win the communication game and limit edge pressure, their playmakers can finish the job. If not, Seattle has the tools to make this a grind. The opening quarter will tell you everything. Keep your eyes on the left side, the cadence, and the ball coming out on time.
